vided with a port 27, which extends longitudinally in said valve Vand then outwardly through one side thereof to register with an opening 28 in a nozzle 29, which is connected to a screw threaded nipple 30 on the valve casing 21., and extends to near the outer end lof the mixing tu'be 31, which communicates with the body of the mixer 16 just below the floor 20 thereof. The nozzle 29 is provided with a guard 32 which has openings 33 for the intake of air which4 is mingled with the gas as it passes through the opening 34 of "the guard or cap 32 and into the tube 31 of the mixer. The tubes 19 and 3l of the mixer are extended through the openings 11 and 12 respectively of the casing 10, so that the mixture of gas and air will take place externally of the casing 10, thus precluding any possibility of the discharged burnt gases being mixed with the supply of. gas. Secured to the lower portion of the mixer 16 is a coupling 35 to which is secured a tube 36 which is provided with a strainer 37 just below the coupling 35 for breaking up the mixture of air and gas and for catching any foreign substances that may be borne thereby. A suitable burner tip (not shown) carrying one or more mantles can be secured to the tube 36, as is apparent, thus enabling the lamp to be equipped with a single mantle burner cr a burner having a group of mantles as may be desired. Horizontally located on the tube 36 is a. disk 38 which has a series of radially arranged blades 39.

pitched at angles, as shown in Fig. y1 of the drawings. This disk and the blades thereof are employed to facilitate the draft through the inner casing 40 which surrounds the portion 47'of a group mantle carrier 48 directly into the lower portion of said mixer. It is obvious thata single mantle carrier can be thus secured into the lower portion of the mixer 16 instead of the group carrier which, as before stated, can also be done when the construction shown in Fig. 1 and above described is employed.

From the foregoing and by reference to the drawings, it will be understood and clearly seen that by employing my imp-rovements the hydrocarbon or gas supplied through the pipe 15 and mixer 16 will be ,commingled with freshA air drawn or forced into the outer end of the tube 31 by the jet of gas passing through the nozzle 29, and that such mixture will vbe free from burnt charges of discharged gases, as -the tube 31 receives its supply of the mixture of air and gas externallyof the casing 10, thus affording an almost perfect combustible mixture. As the valve 22 1s connected to the operating rod 25, which may be detached therefrom if desired, it is obvious that said valve may be turned so as to regulate the supply of gas discharged through the nozzle 29 without the usual jar or vibration incident tothe pulling of chains ordinarily used for turning such valves, which jars or vibrations soon destroy the effectiveness of the mantles. It is further manifest that by the use of my improvements a lamp provided .with means for interchangeably connecting a single mantle burner tip or a group bearing mantle burner tip with the mixer of the lamp is furnished.

Having thus fully described my invention what I claim as new and desire to secure by mixer 16.and tube 36, and is secured at its Letters Patent is-L upper portion to the upper inner portion of the casing 10, yet in such a manner that it will be spaced from said casing at the lower portion of the latter.

Secured to the lower part of the casing 10 by means of a hinge 41 is a globe holder or carrier 42, which is provided with a number of set screws 43, to be used for clamping the upper portion of the globe 44, which fits in the ring-lilre holder 42, as is clearly shown in Fig. 1 of the drawings. The lower part of the casing 10 is provided at suitable points with slots 45 to receive the set` screws 43 when the holder 42 is raised. to" its normal position, in which position it may be retained by means of a catch 46 pivotally secured at its upper end to the casing 10, and depending at its other end to the lower portion of the casing. l

' In Figs. 4 and 5 of the drawings is' shown a modification in the manner of connecting `the mantle carrying burners to the mixer 16, which consists in dispensing with the coupling 35 and tube 36 and screwing the upper In a gas lamp, the combinationwith a pipe for the supply of gas, of a mixer. corn'- municating therewith and depending therefrom, said mixer having a pair of laterally disposed conduits extended therefrom, one above the other, a partition in the mixer between said conduits, a .vertically disposed valve casing connected at its upper portion to the upper one of said conduits at the outer end thereof, a jet nozzle extended from said casinfy below the. u er conduit and in alinement with the outer end of the lower conduit, an apertured guard surrounding the discharging end of said nozzle and spaced from the free end of the lower conduit, a

rotary valve in the lower portion of saidl valve casing to control the'fiow of gas from said casing through said nozzle, and a depending rod connected to said valve to turn' the same.
